Need some help here....

My 2001 2.0 petrol is smoking badly on startup for approx 2 mins, smells really rich on fuel.
Garage told me Valve stem seals, got them replaced and still producing smoke.
Compression seems fine, head gasket replaced when seals were done.

Have noticed that engine revs rise when clutch depressed (when car is moving).
Once car comes to a halt, revs drop, still ticks over slightly higher than normal.
Throttle body has been cleaned, so has air flow meter and idle control valve.
Wondering which of the above (if any) may be the culprit.
Have also read it may be some breather pipes or crank breathing related?
Have found a multitude of explanations on differing sites, trying to whittle down.

Any suggestions?
